Summary:
The revised Book-E spec, adding the specification for the MMUv2 and e6500,
includes a hardware PTE layout for indirect page tables. In order to support
this in the future, migrate the PTE format to match the MMUv2 hardware PTE
format.
Test Plan: Boot tested on a P5020 board. Booted to multiuser mode.

- Bind SPIs in the Distributor
- Don't bind its_dev to collection. Keep track of the collection
IDs for each LPI.

rather be called on each interrupt. Move in to the arm_cpu_intr()

Separate interrupt descriptors lookup from allocation. It was possible
to perform config on non-existing interrupt simply by allocating spurious
descriptor.
Must lock the interrupt descriptors table lookup to avoid mismatches.
This ought to prevent trouble while setting up new interrupt
and dispatching existing one.
Use spin mutex rather than sleep mutex. This is mainly due to lock in
arm_dispatch_intr.
This should be eventually changed to a lock-less solution without
walking through a linked list on each interrupt.

the sign bit doesn't cause an overflow. The overflow manifests itself
as a sorting index wrap around in the middle of the sorted array,
which is not a problem for the LRO code, but might be a problem for
the logic inside qsort().

This is a prelude to intr-ng support for MIPS boards that need it -
notably the CI20 port from kan@ that's upcoming, but also work that
Stanislav is doing for the Mediatek platforms.
This is the initial platform dependent bits in include/intr.h, some
#defines for the nexus code for the intrng initialisation/runtime
bits, some changed naming (which I'll fix later to be the same, much
like what I did for ARM intr-ng) in exception.S, and the first cut
at a PIC.
Stanislav and I refactored out the common code for intrng support,
so the mips intrng definitions are quite small (sys/mips/include/intr.h.)
This is all work done by kan@, which stanislav has been cherry picking
into common code for his mediatek chipset work.
Tested:
* Carambola2 - no regressions (not intr-ng though!)

This is ongoing work from Damjan Jovanovic to improve ext4 read support
with sparse files:
Keep track of the first and last block in each extent as it descends down
the extent tree, thus being able to work out that some blocks are sparse
earlier. This solves an issue on r293680.
In ext4_bmapext() start supporting the runb parameter, which appears to be
the number of adjacent blocks prior to the block being converted in the
same way that runp is the number of blocks after, speding up random access
to mmaped files.

When a user defines "jail_list" in rc.conf the jails are started in the
order defined. Currently the jails are not are stopped in reverse order
which may break dependencies between jails/services and prevent a clean
shutdown. The new parameter "jail_reverse_stop" will shutdown jails in
"jail_list" in reverse order when set to "YES".
Please note that this does not affect manual invocation of the jail rc
script. If a user runs the command
# service jail stop jail1 jail2 jail3
the jails will be stopped in exactly the order specified regardless of
jail_reverse_stop being defined in rc.conf.
